Suppose you are to play a gambling game where the chance of gaining equals to that of loosing and you are having only $10.0. If you lost, you will loose all you bet and if you win, you will gain 2 times the amount betted. The following are the only possibilities:

1. Remain with your $10.0 and do not enter this game as it is risky2. Bet $2.0 and loose it at all, otherwise gain $4.03. Bet $4.0 and loose it at all, otherwise gain $8.04. Bet $6.0 and loose it at all, otherwise gain $12.05. Bet $8.0 and loose it at all, otherwise gain $16.06. Bet all $10.0 and loose it at all, otherwise gain $20.0

How much are you going to bet?
